3d heart model

Highly detailed anatomically accurate human heart, designed as a modular explodable 3D educational model. Every anatomical component must be generated as a separate mesh/object with clean topology and clear boundaries — NOT fused into one solid structure. Include individually selectable parts such as left atrium, right atrium, left ventricle, right ventricle, aorta, pulmonary artery, pulmonary veins, vena cava, heart valves, coronary arteries, cardiac veins, myocardium layers, and septum. Each component should have proper spacing and segmentation for interaction and selection in a 3D/XR application. Requirements: Separate mesh/object for every anatomical structure No merged geometry Organized hierarchy/group naming Clean edge flow and optimized topology Realistic medical anatomy PBR materials Educational/scientific visualization style Exploded view layout with slightly separated components High poly but optimized for real-time XR/Unity/Unreal Centered model, proper scale White or tr
